Learning Structured Representation for Text Classification ...

gradient methods (Sutton et al. 2000), aiming to maximize the expected reward as shown below. J() = E (s t;a t)˘P (s t;a t)r(s 1a 1 s La L) = X s 1a 1 s La L P (s 1a 1 s La L)R L = X s 1a 1 s La L p(s 1) Y t ˇ (a tjs t)p(s t+1js t;a t)R L = X s 1a 1 s La L Y t ˇ (a tjs t)R L: Note that this reward is computed over just one sample, say X= x ...
